Abstract

The production scheduling problem is in the kind of flowshop with n jobs and m machines, to get the order of the schedule for allocating operations of the jobs to the available machines so as to get the minimum total time for completion of all job or commonly called makespan. This study uses an optimization technique approach with the PSO algorithm to get minimum makespan on the ordered flowhop scheduling problem. The performance of the scheduling algorithm presented is evaluated by testing on a benchmark data set of 240 variations in the combination number of jobs and machines. The minimum measure is obtained as a result of scheduling with PSO, whose process stops at a certain iteration when in the last 10 iterations there is no change in the value of a better makespan. The performance of the PSO algorithm is efficient at regular flow scheduling with the use of the most iterations of 19 iterations and the longest execution time of 28.42 seconds or less than half a minute, namely scheduling instances with the largest number of machines and jobs. In this research, only the analysis of the resulting minimal forward and the time of execution was carried out. Further research can be extended by not only measuring the minimum makespan, such as measuring total flowtime, total tardiness, and others.

Abstract

Abstract. This research was conducted on high school students in class XII, which aims to determine the extent of students' motivation and interest in learning, when distance learning (PJJ) is applied to Mathematics subjects using Google Jamboard which is an interactive learning medium. This research is conducted in the 2021/2022 academic year in the odd semester which involves 35 students. The instruments in this study were student activity observation sheets, learning implementation observation sheets and student response questionnaires. The results of this study will be seen to increase students' motivation and interest in learning by using Google Jamboard as an interactive learning medium.Abstrak. Penelitian ini dilakukan pada peserta didika tingkat SMA kelas XII, yang bertujuan untuk mengetahui sejauh mana motivasi dan minat belajar peserta didik, ketika pembelajaran jarak jauh (PJJ) diberlakukan pada mata pelajaran Matematika dengan menggunakan google jamboard yang merupakan media pembelajaran bersifat interaktif.  Penelitian ini di tahun ajaran 2021/2022 pada semester ganjil yang melbatkan sebanyak 35 orang peserta didik. Instrumen pada penelitian ini adalah lembar observasi aktivitas siswa, lembar observasi keterlaksanaan pembelajaran dan angket respon siswa. Hasil dari penelitian ini akan dilihat meningkatnya motivasi dan minat belajar peserta didik dengan menggunakan google jamboard sebagai media pembelajaran interaktif.
